SMT production line uses RFID to detect PCBs to reduce error rates and simplify documentation requirements

The printed circuit board (PCB) communicates with the SMT production line and contains all relevant manufacturing data. This is achieved through the HARTING RFID-4-SMT automatic identification solution. The solution reduces error rates and radically simplifies documentation requirements to form a single-volume automated printed circuit board (PCB) production base.



When manufacturing a printed circuit board ( PCB), a small UHF RFID chip is inserted into the blank or later installed as a component. From this point of view, each station in the manufacturing process can write and read manufacturing data on the RFID chip. It can even store unplanned events such as machine failures.


All of this benefited from HARTING's cutting-edge UHF RFID technology, which was exhibited at the Munich International Electronics Show (November 13-16, 2018, Munich/C2 Hall, Booth 548). The technology is easy to implement thanks to the Ha-VIS LOCFIELD® antenna based on coaxial cable and the flexible UHF RFID reader Ha-VIS RF-R350 based on the MICA® platform. The antenna field follows the coaxial conductor and is capable of communicating with multiple printed circuit boards (PCBs) on a printed circuit board (PCB) panel at full production speed.


Readers and antennas can be easily integrated into new and old systems. The compact design and IP67 protection are also very easy to upgrade. Therefore, comprehensive data can be integrated into the production system at any time, although it is not absolutely necessary.


Benefiting from the modular and open software architecture of the UHF RFID read/write device Ha-VIS RF-R350, data can be preprocessed in the reader. Data storage conforms to ISO standards and the GS1 standard for the transport of goods. It applies not only to the ID of the printed circuit board (PCB) itself, but also to the process and manufacturing data stored in the user memory of the RFID chip. So all this is transparent and can be easily used by third parties in the future.



Utilize the printed circuit board (PCB) ID characteristics throughout the production lifecycle



UHF RFID technology is used on printed circuit boards (PCBs) and can be fully utilized throughout the life of a printed circuit board (PCB). This technology is especially suitable for warehouse and logistics processes by reading multiple printed circuit boards (PCBs) in batches through aluminum foil and carton packs without light contact. In addition, information can be read even if a printed circuit board ( PCB) is already installed in the application. As long as the housing is not completely made of metal and meets some basic physical principles, the information in the RFID chip can continue to be used and updated. The functionality provided by UHF RFID technology is always available before the printed circuit board (PCB) is disposed of, and can facilitate and improve a variety of applications.
